I am trying to use the reduce pattern on a Javascript Array of objects. But, instead of doing this in a single reducer, I want to be able to use a different reducer based on a condition set for each of the items in the array. So, it would look like the following.
const FOO_MAP = new Map([
["Foo1", Bar1],
["Foo2", Bar2]]
);
function calcTotal(values) {
if(values == null) return 0;
return values.reduce(FOO_MAP.get(value.field));
}
function Bar1(previous, curr){...}
function Bar2(previous, curr){...}
Is this possible? Thanks!

values.reduce((acc, el, i) => FOO_MAP.get(el.field)(acc, el, i), 0);
